Cara watches two astronauts spacewalk to examine microbes on the ISS

This week two astronauts will undertake a spacewalk from the International Space Station (ISS) while collecting samples from the outside of the station for use in scientific research. The two astronauts are Loral O’Hara from NASA and Andreas Mogensen from the European Space Agency (ESA), and the spacewalk will take place on Thursday, October 12.

If you want to watch the event live, NASA will be broadcasting the entire spacewalk live on the NASA TV channel, and we have details on how to watch it below.

What to expect from space travel

(June 9, 2023) — NASA astronaut and Expedition 68 Flight Engineer Woody Hoburg rides the Canadarm2 robotic arm while maneuvering a solar array toward the truss structure of the International Space Station 257 miles above the Pacific Ocean. In the background, there is a SpaceX Dragon crew vehicle that docked into the front port of the Harmony module on March 3 carrying four SpaceX Crew-6 crew members. NASA

Spacewalks are usually carried out to perform maintenance on the station, such as a series of power system upgrades involving astronauts. installed new solar panels on the exterior of the station over the past few years. However, this event will be a little different, because the aim is for scientific research as well as maintenance.

“On October 12, O’Hara and Mogensen will exit the Quest station’s lock chamber to collect samples for analysis to see whether microorganisms may be present on the outside of the orbital complex. “They will also replace high-definition cameras on the station’s port frame and perform other maintenance work to prepare for future space travel,” NASA said in a statement. renew.

To search for microorganisms outside the station, astronauts will use a swab that they will pass over the outer surface using a special tool. These swabs can then be tested for the presence of bacteria or other types of microbes, to see if anything survives in the harsh environment outside the station. In addition to the vacuum of space, the outside of the station also experiences varying temperature ranges depending on whether it is in the sun or in the shade, and is also exposed to more radiation than we experience on the Earth’s surface.

Studying the microorganisms that can survive in such environments is important for keeping stations clean and free of potentially harmful microbes, but can also help scientists learn about potentially beneficial microbes that can survive harsh conditions.

How to watch space travel

The spacewalk will be broadcast live with coverage starting at 8:30 a.m. ET (5:30 a.m. PT) on Thursday, October 12. The spacewalk is scheduled to begin at 10 a.m. ET (7 a.m. PT) and will last for about six hours.
